gpio: make of_get_named_gpiod_flags() private
of_get_named_gpiod_flags() is visible and directly usable by GPIO consumers, but it really should not as the gpiod interface relies on the simpler gpiod_get() to provide properly-configured GPIOs. of_get_named_gpiod_flags() is just used internally by gpiolib to implement gpiod_get(), and by the old of_get_named_gpio_flags() function, therefore it makes sense to make it gpiolib-private. As a side-effect, the unused (and unneeded) of_get_gpiod_flags() inline function is also removed, and of_get_named_gpio_flags() is moved from a static inline function to a regular one in gpiolib-of.c This results in all references to gpiod_* functions in of_gpio.h being gone, which is the way it should be since this file is part of the old integer GPIO interface. Changes since v1: - Fixed compilation error when CONFIG_OF_GPIO is not defined - Fixed warning due to of_gpio_flags enum not being declared in private gpiolib.h header Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
